Explanation :

Mahima is sister of Disha and they are daugthers of Akash and Priya. 

Now, Disha is married to Ankur who’s sister is Kanika.

∴ Ankur and Kanika’s parents are Garima and Arpit.

Kanika is married to Harshit and has two kids Ankit and Pavitra.

Pavitra is grand-daughter of Garima and Arpit hence, she is a female.

We cannot determine the gender ofo Arpit, Garma, Akash, Priya and Ankit.

Neha is Ankur’s daughter and Kanika is Ankur’s sister. So, Neha is Kanika’s niece.

Garima is Ankur’s mother and hence kanika’s mother as well while Harshit is Kanika’s husband. So, Garima is Harshit’s mother-in-law.

Arpit is the father of Ankur and Disha is Ankur’s wife. So, Arpit is Disha’s father-in-law.

Explanation :

There are three couple and three generations. 

Bharat and Kirti are the eldest pair i.e. in the first generation. However, their gender is unknown. 

Since Kirti has only one child, Manav, and Manav has a daughter-in-law, Manav is married. 

Hence, there is one couple in the second generation and one couple in the third generation. 

Since there is a brother-sister pair, it can either be in the first or third generation. 

Riya is the mother of Nipun. Nipun cannot be in the first generation (as that would increase the number of generations to 4) or second generation (as Manav has no siblings). Hence, Nipun is in the third generation. 

Hence, Nipun’s mother, Riya, has to be in the second generation. i.e. Riya is the wife of Manav. 

Since the third generation should have a couple and a brother-sister pair, Nipun has a wife and a sister.

Rishita plays hockey while the daughter-in-law of Manav (i.e. wife of Nipun) plays chess. 

Hence, Rishita is the sister of Nipun and her sister-in-law, Shrishti, is the wife of Nipun. 

Finally, the games played by each person are: Bharat - Poker; Kirti - Bridge; Manav - Snooker, Riya - Carrom, Rishita - Hockey, Nipun - Shooting, Shrishti - Chess. 

The entire family tree is as shown below:

[Note: We cannot assume gender of people just by their names.]

Since the gender of Bharat and Kirti is unknown, either of them can be the grandfather of Rishita. 

Hence, option (e).
